Travelling speed too high.
Reduce travelling speed. Slow down at
the beginning of the baling process until
the picked up crop rolls in the bale
chamber.
The machine is not hitched
horizontally.
Hook in machine higher at the front.
Adjust drawbar height so that the transfer
from the pick-up to the channel is more
even.
The transfer of short crop
from pick-up to cutting
roller is poor.
The machine is too low at front.
Hook in machine higher at the front.
Adjust drawbar height so that the transfer
from the pick-up to the channel is more
even.
The wrapping material
tears in the middle if the
bales are barrel-shaped.
